IMPROVEMENT IN BREECH-LOADING FlREARlifiS.

2"'0 @ZZ whom, t may concern.-

Be it known that I, JOHN C. NYE, of Cin cinnati, in the county of Hamilton, in the State of Ohio, have invented a new and Improved Breech-Loading Fire-Arm; and I do hereby declare that the following is a4 full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, and to the letters of refer ence marked thereon.

Figure l is a side view of the arm with all parts in place. Fig. 2 is ahorizontal section, the upper part takenoi, showing the parts in place as when loaded. Fig..8 is the same as Fig. 2, with the plunger or breech-pin drawn out as in loading. Fig. /Iis a side View of the arm with the breech-pin drawn out, showing the opening where the cartridge is inserted. Fig. 5 is a longitudinal section of the breechpin, showing the groove and guide. Fig. 6 is a transverse or cross-section of the breech-pin, showing the groove in the under side.

A is the barrel of the arm. Bis the breechpin or plunger by which the .cartridge is pushed up to its place in the chamber, as seen in Fig. 2, the breech-pin B forming a perfect joint with the barrel at c, the breech-pin B being kept steady in moving out and in by the guidef entering into the groove g, as seen in Figs. 5 and 6, the end of thegroove gbeing at lz, preventing the breech-pin B from coming farther than is necessary1 to make room for the insertion of the cartridge. C is a key or gate Which holds the breech-pin B in its place when l shut Clown, having a firm bearing at ee @,While the breech-pin B has a hrm bearing on C at d, as seen in Fig. 2. D is a hingejoint, upon which the key or gate C swings, on the head or base of the breech-pin B. E is a spring, which holds the key or gate C in its place open or shut down. F is a screw that holds the spring E firmly to its place on the key or gate C and breech-pin B, by the turning of which the spring E may be graduated. The screw F is also used as a handle to open the gate or key O with. G is a spring which holds hammer K when key O is open, but may be dispensed with. Cartridge, as seen in Figs.y 3 and 4, which is closed by the key or gate C', as seen in Fig. l. AI is the stock ofthe arm. Jis the lock. the cock or hammer. Lis the cone or nipple. 4 M is the trigger'. N is the guard. O is a lever and spring attached to guide f, bythe moving of which the breech-pin B may be taken out of its place ifit is wished to disable the arm. P is a bevel to make room for the insertion of the cartridge.

Vhat I claim aslny invention, and desire to secure by Letters Patent, is-

The key or gate C and the mode of applying the same to firearms, substantially as described.
